T @ZZ whom t may concern.-

Be it known that we, DANIEL J. BREW and HARRY B. MALLoRY, citizens of the United States, residing at Danbury, county of Fairfield, State of Connecticut, have invented a new and useful Hat-Forming Machine, of which the following is a specification.

Our invention has for its object to provide a hat-forming machine so constructed that the formed hats may be removed from the cone without removal of the cone itself from the table by which it is carried, thereby effecting a great saving in the cost of production, as the capacity of the machine is increased and the cost of labor in running it is ,greatlyreduced With these ends in view we have devised the simple and novel hatforming machine which We will now describe, referring to the accompanying drawings,form ing part of this specification, and using reference characters to designate the several parts.

Figure 1 is a side elevation of the machine complete. Figs. 1a and 1D are detail views illustrating means for regulating the air-current in the chute; Fig. 2, a plan View, on an enlarged scale, of the forming-box, the exhaust-pipe being in section on the line 2 2 in Fig. 3; Fig. 3, a central section on the line 3 3 in Figs. 2 and 4; Fig. 4, an inverted plan view of the top of the forming-box and the table by which the cone is carried, the cone being in section on the line 4 4 in Fig. 3 and the nozzles and regulating device removed; Fig. 5, a detail view of the stripper removed; and Figs. 6 and 7 are enlarged detail sectional views, corresponding with Fig. 3, illustrating the operation of the stripper, Fig. 6 showing the stripper in its normal position, as in Fig. 3, and Fig. 7 showing it in iis operative position, as when starting a hat-body from a cone.

A denotes the feeding-apron; B, picking mechanism; C, a chute for conveying the picked stock to the forming-box; D, one of a pair of brackets to which the chute is secured; F, the forming-box as a whole; G, the eX- haust-pipe, which is provided with a shutoff 54, and H the cone as a whole. The top of the forming-box, which we have indicated specifically by 10, is provided with a central opening 11, having a shoulder 12, which receives the table J. The table is provided upon its under side with a circular iange 13, which travels upon rollers 14, carried by brackets 15 on the under side of the top. The table is also provided on its under side with a gearwheel 16, which meshes with a pinion 17, carried by a shaft 18, driven in any suitable manner, as by means of a belt (not shown) running overa belt-pulley 19. On the upper side of the table and surrounding a central opening 20 therein is a flange 21, having a circular groove 22, which receives the end of the exhaust-pipe, so as to form a relatively tight joint, it being of course essential that the table rotate freely and also desirable to shut oi as nearly as possible the passage of forming-box, to which it is detachably secured in any suitable manner, as by turnbuttons 25.

The cone proper may be of any ordinary or preferred construction. The feeding and picking mechanism likewise is of ordinary construction. Air enters the chute to carry along the picked stock at an opening 26 in the under side thereof, (see Figs. 1, 1, and 1",) said opening being provided with a gate 27, by which the quantity of air entering the chute may be regulated. We have shown the gate as provided in its ends with notches 28, which are engaged by pins 29 to hold the gateatanydesiredadjustment. Theforward end of the chute, as at 30, is made of iiexible material, and the bottom is pivoted (see dotted lines, Fig. 1) and is provided with an adjusting device 31, by which the bottom may be raised or lowered to modify and regulate the deposit of fur on the cone. The cone is also provided with the usual internal regulating device 32, the adjustment of which increases or diminishes, as required, the relative amount of stock deposited upon the tip of the cone. As already intimated, however,

IOO

special use to which the machine may be applied or in accordance with the judgmentof the manufacturer.

K (see Figs. l and 2) denotes-a sprinkler of any ordinary or preferred construction attached to a hot-water-supply pipe 33, shown as provided with a valve 34. It will be understood from the drawings that the sprinkler is located back of the forward end of the chute and at one side thereof, so that water thrown by the sprinkler will not strike the forward end of the chute, so as to cause the stock to adhere thereto. In the drawings we have shown the sprinkler as curved, so as to correspond approximately with the the curvature oi' the tip of the cone. This, however, is a detailof construction that may be adopted or not, depending upon the requirements of use.

L denotes a stripper which is made in the form of a ring adapted to slide over the base of the cone. We have shown the base of the cone as made with vertical parallel sides, over which the inner vertical face of the stripper just slides freely, the outer face of the stripper being beveled, as at 35. This stripper is supported and held at its retracted or inoperative position by a series of springs 36, which are secured to the cone in any suitable manner. In the present instance we have shown ring 23 as provided with sockets 37, in which the springs are secured by pins 38. lVe have shown the stripper as operated by means of a lever 39, which is pivoted to the under side of top lO, as at 40, and whose forward end consists of branches which rest upon the stripper. In order to provide for convenient adjustment to different-sized cones and strippers, we have shown the branches as hinged to the body of the lever, as at 42, and the branches as retained in operative position by a tie-bolt 43. In practice the ring 23 is made of suitable size to just pass within the base of the special size of cone to which it corresponds. The extreme diameter of the flange 24, however, is always the same, so that cones of different sizes may be secured to the table by the turn-buttons.

As a means of removing the formed and sprinkled hot bodies from the cone after they have been started by the stripper we provide a pipe 44, which supplies air or steam under pressure and is provided with a valve 45. This pipe 44 terminates in one or more nozzles 46 near the inner periphery of the cone. In the present instance we have shown regulating device 32 as provided with a shank 47, which engages a tubular holder 48, attached to or made integral with pipe 44.

M denotes a receiving-apron, upon which the hat-bodies drop from the cone. W'e have shown the receiving-apron as carried by rollers 49, one of which is within the forming-box, the other outside thereof, the inner roller being adjustable in slotted brackets 50, so as to permit the inner end of the apron to be raised or lowered as maybe required, and the shaft 52 of the outer roller being provided with a belt-pulley 53 to receive a belt, (not sho\vn,) by which the apron is driven. The apron is shown as passing through an opening 5l in the sido of the forming-box.

The operation is follows: The stock for the bodies is weighed and placed upon the feeding-apron, is picked, passes through the chute, and is drawn upon a rotating cone in the usual manner, the novelty of this portion of our invention lying in the fact that the cone is carried by an overhead table. As soon as the stock for a body is blown upon the cone without stopping the rotation of the table the valve in the hotwater-supply pipe is opened in any suitable manner either by hand orautomatically, and the body upon the cone is sprinkled, the exhaust acting to draw the hot water into the body and causing it to become thoroughlysaturated. An instant later the shut-off in the exhaust-pipe is operated either by hand or automatically to stop the passage of air through the cone and into the exhaust-pipe. We wish it distinctly understood that the special mode in which the shutting off of the air in the exhaust-pipe is effected is not of the essence of our invention. In the drawings we have shown the exhaustpipe as provided with a shut-oif in the form of an ordinary damper. Any other means of stopping the exhaust may, however, be adopted, if preferred, and will be within the scope of our invent-ion. As soon as the body is saturated the stripper is operated either by hand or automatically, and practically sim ultaneously with the operation of the stripper the valve in pipe 44 is operated either by hand or automatically, allowi ng air or steam under pressure to escape at the noZZles,and the body is thus gently but quickly removed from the cone and caused to drop down upon receiving-apron M, by which it is removed from the forming-box. All this, it should be understood, takes place not only without removal of the cone from the table, but without stopping the rotation of the table, the operations of opening and closing the hotwater-supply pipe, shutting off the exhaust, operating the stripper, and opening and closing pipe 44 being performed, as already stated, either by hand or automatically, the special mechanism by which these operations are performed not being of the essence of our presentinvention. The instanta hat-body has been removed from the cone and still without stopping the rotation of the cone the formation of another hatbody thereon may be commenced. We nd in practice that the sprinkling of the bodies upon the cone causes suicient compacting and felting of the stock, so that the bodies may be handled without difficulty, and that with our present forming-machine We are enabled to produce hat-bodies equal to the best, that the capacity of the machine is in excess of any hat-formin g machines heretofore built,
